Question

In Data mining, ______ is a method of incremental conceptual clustering.

• A. STRING
• B. COBWEB
• C. CORBA
• D. OLAD

Answer 1

as is B

COBWEB is an incremental system for hierarchical conceptual clustering. COBWEB was invented by Professor Douglas H. Fisher, currently at Vanderbilt University.^[1][2]

COBWEB incrementally organizes observations into a classification tree. Each node in a classification tree represents a class (concept) and is labeled by a probabilistic concept that summarizes the attribute-value distributions of objects classified under the node. This classification tree can be used to predict missing attributes or the class of a new object.^[3]
